ALKALi-FREE DETERGENT FOR SCOURING- AND DYEING AND PROCESS OF MAKING No Drawing.

To all whom it may concern:

Be itknown that I, JOHN BARRINGTO'N, a citizen of the United States, residing in the city of Boston, county of Suffolk, State of Massachusetts, have invented a new and use- Detergent for Securing and Dyeing and Process of Making Same, of which the-following is a specification.

Specification of Letters fatent.

My invention relates to a new and useful detergent or soap dye, method of producing, and process for employing the same, the detergent consisting of a neutral vegetable oil soap, sulfonated castor oil, and an anilin color in suitable proportions, and in the i in adding a neutral product which is capable of forcing boiling dye bath, and on the material, both animal and vegetable fibers, which will color same thoroughly and permanently.

My new compound consists of a mixture containing a'neutral vegetable oil soap, such sulfonated cas-.

tor oil, and an anilin. color or colors, which may be of the color desired, and the color employed is of such a nature that it will dye vegetable and animal fibers, such as cotton, wool, silk, etc., and I employ a neutral vegetable oil soap, such as neutral cocoanut oil soap, for the reason that no free alkali is contained therein, as the animal fibers would not color well, should there be any free alkali. Moreover, the material is cleansed while the dyeing process is going on by using this neutral vegetable oil soap, will not be afi'ected perceptibl by a neutral product. such as sodium ch orid, which is subsequently added to force the dye on the vegetable and animal fiber. By reason of this combination of elements, the goods, either articles or material, when subjected to the action thereto, are thoroughly secured and dyed in the same operation, the scouring being first accomplished, and the dyeing thereafter, by reason of the addition to the composition of the neutral product. Due to the softening qualities of the sulfonated castor oil, the goods,

fihe method of producing the detergent an example, in a soap color, I take seams, should may be varied, but as are softened and vdye from staining the same,

The method or process of scouring'and dyeing with the soap dye consists in subjecting the articles or materials to the action of the soap dye (consisting of neutral vegetable oil soap, sulfonated castor oil and anilin dye), dissolved in a boiling bath of water, and boil same for a suitable time, such as five minutes. I then add a chemically neutral substance, such as sodium chlorid, which has the power to force the dye out of the boiling dye bath and onto both the animal and vegetable fibers at the same time, and I bdil slowly for a suitable time, say for fifteen or twenty minutes. The goods are then removed and washed in cold water. By adding the neutral product or neutral salt, which is neither acid nor alkali,

it will force the dye from the dye bath on all fibers, cotton, wool, silk, etc. (animal and vegetable fibers), and'by first subjecting the goods to the soap dye, the same are thoroughly scoured or cleansed without the dye Patented May 11, 1915. I

By this process, I obtain a color which is faster and brighter than if dyed in' other manners.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is

'coloradapted to dye both vegetable and animal fibers.
